How to use this finance calculator

Use this finance calculator to combine a present lump sum with recurring payments and compounding. It is useful for accumulation planning when you know the starting capital, periodic cash flow, rate, and timeline.

  1. 1

    Enter present value

    Use the amount available at the beginning of the scenario.

  2. 2

    Add periodic payment and rate

    Enter the recurring cash flow and a rate aligned with the period and risk.

  3. 3

    Review the solved future value

    Compare how much comes from initial capital, payments, and time.

Worked planning example

Example: combine a lump sum and annual deposits

Set up

Model an opening balance plus equal recurring payments over a fixed term.

Compare

Reduce the rate or remove the opening balance to isolate each driver.

Takeaway

Time-value-of-money results are sensitive to matching the payment frequency and rate convention.

Keep periods and rates consistent

A valid calculation requires the rate, payment timing, and number of periods to use compatible units.

  • Do not mix monthly payments with an unconverted annual period.
  • Use a net rate after relevant fees.
  • Confirm whether payments occur at period end.

Frequently asked questions

What is time value of money?

It is the principle that money available today can have a different value from the same nominal amount in the future because it can earn a return.

Can this solve every finance variable?

This page models a common future-value case. Other unknowns may require present-value, rate, or payment calculators.

Why does payment timing matter?

A payment made earlier has more time to compound than one made at the end of a period.
